baby won’t let me put him down

my baby is 3 months old and he never lets me put him down.. i’ve tried everything.

he just SCREAMS and i’m not talking like a baby cry, i’m talking full blown bloody murder cry (red until purple, choking on own spit, whole body stiff/shaking) and then it’ll take ages for him to calm down again. i’ve even just tried walking away and letting him cry, he screamed for 40 minutes with no end in sight before i picked him up again.

he won’t sit in a bobbi, a swing, car seat (which is probably the worst, he HATES the car seat and driving in the car and screams the ENTIRE car ride, which sucks because his doctor is an hour away..) anything or anywhere, not even if i’m right next to him.

i can’t even put him down while he naps because he instantly wakes up as soon as i put him down and starts screaming.

my partner isn’t here right now because he had to go to his aunts funeral so it’s just me and the baby, i haven’t been able to shower fully or eat an actual meal in over a week..

idk what to do, he won’t even play by himself, i have to sit him in my lap and he’ll play

please someone help, i exclusively pump feed (he won’t breast feed i’ve tried a million times he’ll just scream on my breast, even the lactation consultant was getting annoyed and just told me to stop, which is how i started pump feeding. i know he can latch though) so i have to put him down for 20 minutes every 2-3 hours and the entire time he screams as if i’m leaving him for dead, even though he’s sitting right in front of me !

EDIT: he won’t do tummy time on a play mat, we try every day, as soon as i put him down- screams. i wouldn’t care if it was normal baby crying but this is seriously like i’m trying to kill him cry’s. usually my partner and i do just hand the baby off to each other because we both know how he is but i’m going to be without my partner for over a month possibly two.. it seems like this screaming thing won’t let up

EDIT 2: he won’t sit in a wrap or carrier. and he HATES the bobbi, he’s so strong too that i can’t leave him in it anyways because he rolls or flips out of it (he’s done it multiple times..). i put him on the floor to try to do housework but it’s so distracting to hear a baby screaming until he chokes, and he thrashes too so he keeps banging his head on the floor when i have to put him down to pee.
